Providing Engineering and Software Services To The Natural Gas Industry Since 1992
The desktop version of GASCalc™ is our popular suite of analytical tools. It was specifically developed to aid in the design and operation of natural gas distribution, gathering, transmission, plant, and fuel piping systems. It includes routines for calculating a variety of stress, flow, and pressure values for devices and pipe associated with virtually any piping application that transports or delivers natural gas, propane, butane, or hydrogen blended gas mixtures. Its wide range of features provide the ability to investigate piping problems from the wellhead to the burner tip. Some of its features include...
Pipe Flow & Pressure Values - More than twenty-five different industry-related pipe flow equations are supported for sizing and calculating pressure loss across pipe and fittings. Also included are routines for calculating blowdown and venting values, purging and clearing values, fill time, pipe volume, and service line sizing.
Regulator & Relief Valve Values - Support is provided for calculating pressures and flows through a variety of regulator and relief valve devices. The routines allow the analysis of single devices or devices configured in various “station” arrangements. Devices from multiple manufacturers can be compared side-by-side or in combination in a station configuration. Support is provided for both table and equation-based performance data. These routines are perfect for performing annual relief valve capacity checks.
Stress Values - Routines are included for calculating a variety of pipe stress values, including bending stress on pipe spans, thermal expansion and contraction, hoop stress, stress caused by roadway and railway crossings, steel and plastic pipe design formulas, total combined stress, and segment MAOP values.
Meter Sizing - Support is provided for calculating pressure and flows through a variety of meter types, including orifice, diaphragm, rotary, turbine, ultrasonic, and cone meters. Other measurement-related calculation routines are also provided, allowing quick calculation of volumes at different operating pressures, base conditions, or atmospheric pressure conditions.
Gas Properties - Support is provided for calculating various physical and thermodynamic properties associated with a gas composition. Routines are included for calculating compressibility, sonic velocity, specific gravity, heating value (calorific value), viscosity, specific heat, entropy, enthalpy, hydrate formation, atmospheric pressure, average pressure and temperature, and pressure, temperature, and volume values at varying conditions.
Miscellaneous & Utility Routines - A number of routines are provided for calculating a variety of miscellaneous and utility values. Routines include calculation of velocity, hydraulic diameter, flow limiting devices, compressor values, well flow values, line heater sizing, Reynolds Number, anode life, remaining strength of corroded pipe segment, container volume, energy and dimensional units conversion, heat loss and gain across devices and piping, and value interpolation and extrapolation. One convenient routine estimates gas loss from a punctured or severed line.
The GASCalc™ WebApp is a web (internet) based version of our popular GASCalc suite of analytical tools. It allows Users to perform calculations from any device that can access the internet - including tablets and mobile devices.
Some of the most popular GASCalc calculation routines are included in the Web-Based Application, including routines for the calculation of gas properties, meter values, pipe flow, regulator and relief valve values, dimensional units, and energy conversion.
Custom applications and interfaces can be provided for use on company-specific internet or intranet, support, or promotional sites.
Pricing & Licensing - Currently, there is no fee for using the GASCalc WebApp. It is provided as a complimentary service to our colleagues in the gas industry.

The GASCalc™ API (Application Programming Interface) compliments the GASCalc software by allowing programmatic access to selected calculation routines and methods found in the software. The API allows the GASCalc routines to be embedded in third-party or custom applications to create powerful solutions to serious calculation challenges. The API is available at an additional charge.
The API is a Dynamic Link Library (DLL) containing the gas properties, measurement, pipe flow, regulator, relief valve, and other calculation routines found in the desktop version of the GASCalc software. The DLL can be linked to a User created application or interface - allowing programmatic access to the various GASCalc calculation routines. The GASCalc API is compatible with any development environment that supports the use of a dynamic link library, including .NET, VB Script, VBA, and others.
Pricing & Licensing - The API is provided as a subscription on a per module, per server basis. Discounts are available for multiple modules, multiple subscriptions, and complete package purchases. Please note listed prices are subject to change without notice.
Maintenance & Updates - So long as the annual subscription fee is current, updates to the software are available at no additional charge. Technical support on the use of the software is provided by way of telephone or email communication at no additional fee.
Modules - The API is licensed on a module basis. The individual modules allow access to specific calculation methods and routines. The available modules include:
Compressibility - Provides access to the compressibility factor and density calculations:
